How to view the system console message after Blender crashes?
On windows just run blender from Command Prompt:

Win Key+R

In field type cmd and hit OK. Inside the console navigate to your blender.exe with command

cd c:\Program Files\Blender Foundation\Blender\ (or whatever your path is) 
instead you can also navigate to the folder in the Explorer and SHIFT+Rightclick on the Folder and select Open Comand Promt here

and then type blender.exe

You can also use command line arguments.

Now even if Blender crashes, you will still see the program output in the console.
On OSX use Terminal app and run it like

cd /Applications/Blender
./blender.app/Contents/MacOS/blender

On Linux open terminal and run

cd &lt;blender installation directory&gt;
./blender



You can start blender (or blender.exe) with the option --factory-startup attached to check if a addon or a setting caused the crash
